2,373,710 U LIFT FoarRAoToRBUoKRAKEs j f John v v. Rutledge, Early, Iowa Application February 10, 1943, Serial No. 475,388 9 Claims. (Cl. 56-'-2'7) My invention relates to buck rakes. An object of my invention is to provide a buck rake which can be controlled from the front end of a tractor, and which includes means for tipping the buck rake so that the forward points 1 A further object of my invention is to provide means for, adjusting the degree of movement'of the buck rake.

A further object of my invention is to provide a member in cooperation-with the buck rake which will initiate or force the hay off of the same, which mechanism is further cooperant with said aforesaid tipping mechanism.

A further object of my invention is to provide a simple construction. 7

With these and other objects in view, my invention consists in the construction, arrangement v and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully setforth, pointed out in my claims, and illustrated in the'ac'companying drawings, in which: 1 I,

Figure 2 is a sectional detail taken along the lines 2-2 of Fig. 1,

Figure 3 is a further detail, and v Figure 4 is a plan view of the arrangement.

I have used the character In to designate the forward tractor wheels and the character II the tractor frame. Attached to the member II is the apertured connecting. member l2 which is pivotally attached at l3'to the further'member -14.

tion of the member 24 which is pivoted at '25 to the. U-shaped member 26- which is attached at '21 to the. member IS. The member 24 continues into the vertical portion 28 to which is attached at'29 the cable 30 which passes to the tractor.

The central hollow square tube 15 extends foris attached to the shaft 36 whichshaft 3B is journalled at 31 (see Fig. ,2) tothe brackets- 38 which brackets 38 are welded or otherwise at-- tached to the angularly extending members 39 (see Figs. 2 and 4) which members 39 are rigidly attached at 40 to the square member l6 and are pivoted at 4! to the buck rake itself -Pivotally attached to the sector gear 35 by, means of the pin 42 is the pair of links 43 which links 43 are joined together and are received at 44 between the ears 45 with a pin 46 providing a pivotal connection thereto. The ears 45 are attached to a channel member 41 whichchannelm'ember; in turn, is, attached at 48 to the transverse member 49 of the buck rake and the member 41 continues forwardly, and is also attached to, the. further transverse angle member 50 of the buck rake. Attached to the member 50 are the vertical stande ards 5! in which are suitably journalled the wheels 52 and also attached to the members 50 are the vertically positioned angle members 53 which are pivotally attached to the aforesaid pivots4l. I V

Attached across the members 53 and the corner angles 54 are the transverse bars 55. The fur:

- nel 41.

ther angles 56 provide corner braces, and attached to the members 54 and 56are theside members 51, A latticed push member is indicated at 58 which member includes the transverse slats '59 and the vertically positioned slats 60,

there being a central slat 60. Straddling the central slat 60 are the angles 6| which are attached to the slats 59 and which angles are adapted to further straddle the central tine 62 of the buck rake, andthe ends of the members 6| are also attached to a channel 63 in which is attached the rearwardly extending beam 64 which beam 64 passes between a U-shaped member 65 which U-shaped member includes the horizontal rollers 66 and the vertical roller 61 journalled thereon, and which U-shaped member'65iispivotally attached at 68 at eitherinner side of the chan The beam B4continues rearwardly and is attached to the further. angularly positioned member 69 which includes the point and to which is welded the transverse rod H, the member 69 being attached to the beam 64 by means of the continuation 12. The respective other tines of the rake are indicated by the character 13. Attached at the ends of the tines are suitable metal guards 14. The

tines

62 and 13 are suitably attached to and beneath the

members

50 and 49 and a further brace (see Figs. 1 and 4) is attached across the members 39to provide rigidity thereto.

Now that the structure of my device has been explained, I shall explain the operation thereof. As shown in Fig. 1, the device is in that position wherein the hay gathering tines 13 are in the ground engaging position or wherein the tractor has been backed up slightly and the pin l9 allowed to be forced into the forward opening 32. The tractor is then driven forwardly with the inclined tines 13 passing under the hay, which hay is then forced to the rear of the structure and up against the push member 58. The next step in the operation is that of bringing the tines to the horizontal position as shown by the dotted lines in Fig. 1. To accomplish this result, the cable is drawn rearwardly which swing the lever 28 and correspondingly raises the pin l9 out of the opening 32. The tractor is then driven forward. As the tractor is driven forwardly, the inner hollow member I5 will travel forwardly and until the pin l9 registers with the opening 33, when it will snap into place.

During forward travel of the member [5, the gear rack 34 will also travel forwardly and by virtue of its meshed engagement with the sector gear 35, it will cause the gear to rotate in the direction of-the arrow as shown in Fig. l, correspondingly causing the pivotal point 42 to be forced downwardly thereby forcing the link 43 downwardly and forcing the rear end of the entire rake'structure downwardly which will, correspondingly, bring the tines to the horizontal position as shown. Conversely, to bring the tines to the ground, the action is reversed, which brings the gear to the position as shown in Fig. 1 with the sector gear thereby being rotated in the opposite direction. An additional opening at 16 in the sector gear is provided to allow for varied swinging adjustment of the tines. The hay is then transported after the mechanism is locked to the position desired to dump the same, and the tines are then brought to the ground engaging position in the manner described, and by drawing the cable 30 first to release the pin I9 when again it is locked in the position shown in Fig. 1. The tractor is'then backed up and the point 10 is penetrated into the ground during such backing operation, and as the rake is then drawn rearwardly the push member 58 will remain in fixed position, and as the tines 13 and the central tine 62 are drawn t-herethrough, the

hay on the tines will be forced off of the same.

As soon as the bar H, which bar is slightly longer than the width of the U-shaped member '35, strikes against the U-shaped member 85, this member will be pivoted upwardly in the direction of the arrow releasing the point 'Ill.from the ground and stopping movement of the push member. The push member need not travel all the way off of the tines since it needs only to initiate the removing action of the hay and need only travel a fairly substantialdistance along the tines. It will thus be seen from the foregoing structure that all of the advantages of. ready control of the arrangement such as tipping and the like,

as well as removing the hay, are advantageously performed. It will also be noted that the sector gear, in combination with the gear rake, provides for a very smooth application of power to the tipping arrangement Without any danger of jamming of links or other structures which are not necessary in the present structure. The opening 16, as explained, can be used if it is desired to shorten the movement of the links 43 by mere ly placing the pin 42 through the openin it. The spring 7! i attached at 18 and 19 to the members 23 and I6 respectively to provide retraction of the lever 28.

It will now be seen that I have provided all of the advantages mentioned in the objects of my invention and other'advantages being readily apparent.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents, which maybe reasonably included within their scope.
